Banded geckos (Coleonyx variegatus) were trained, at the rate of five daily trials, on eight intradimensional spatial shifts to a criterion of 80% correct per reversal. In contrast to several previously reported failures to obtain reversal learning, Coleonyx demonstrated significant improvement on both errors and trials to criterion. Their reversal performance compares favorably with that of birds and mammals and a common index of reversal ability, the mean total error, did not differentiate between taxa.

There is often substantial disparity between philosophical ideals and scientific practice. Philosophical reductionism is motivated by a drive for ontological austerity. The vehicle is conceptual parsimony: the fewer our conceptual primitives, the less are our ontological commitments. A general moral to be drawn from my “Functionalism and Reductionism” is that scientific reduction does not, and should not be expected to, facilitate conceptual economy; yet reduction it still is, and in the classical mold. Those who press for the irreducibility of a (...) functional psychology have been seduced by an inadequate account of scientific reduction. Patricia Kitcher is unhappy with my argument because it fails to live up to her philosophical ideals. “The claim that psychology is irreducible to neurophysiology,” she suggests, “rests to a large extent on the fact that, even in principle, neurophysiology is not capable of carrying out the explanatory work of a functional psychology”.

La actividad económica ha existido siempre, la pregunta es ¡qué leyes económicas deben regirla? Curiosamente debemos rescatar valores que hoy las escuelas de negocios dirían "antieconómicos".

This essay engages in a debate with Nancy Fraser and Dorothy Leland concerning the contribution of Lacanian-inspired psychoanalytic feminism to feminist theory and practice. Teresa Brennan's analysis of the impasse in psychoanalysis and feminism and Judith Butler's proposal for a radically democratic feminism are employed in examining the issues at stake. I argue, with Brennan, that the impasse confronting psychoanalysis and feminism is the result of different conceptions of the relationship between the psychical and the social. I suggest Lacanian-inspired feminist (...) conceptions are useful and deserve our consideration. (shrink)

This Companion makes a new departure in Hobbes scholarship, addressing a philosopher whose impact was as great on Continental European theories of state and legal systems as it was at home. This volume is a systematic attempt to incorporate work from both the Anglophone and Continental traditions, bringing together newly commissioned work by scholars from ten different countries in a topic-by-topic sequence of essays that follows the structure of Leviathan, re-examining the relationship among Hobbes's physics, metaphysics, politics, psychology, and religion. (...) Collectively they showcase important revisionist scholarship that re-examines both the context for Leviathan and its reception, demonstrating the degree to which Hobbes was indebted to the long tradition of European humanist thought. This Cambridge Companion shows that Hobbes's legacy was never lost and that he belongs to a tradition of reflection on political theory and governance that is still alive, both in Europe and in the diaspora.

Recent re-evaluation of the question of the exact role of experience in the Cartesian philosophy has emerged from many quarters. The metaphysical issue of innate ideas has been raised by such scholars as McRae and Miles, and a close examination of the role of empirical enquiry and methodology in Cartesian science have been undertaken by Clarke, Garber, Buchdahl and Laudan, to mention only a few. These recent reappraisals of the role of experience in Descartes's philosophy have been cast mostly in (...) twentieth-century terms with a specific view to concerns of the present. ;My research centres on an examination of the philosophical works of three Cartesians, Antoine Le Grand, Robert Desgabets, and Pierre-Sylvain Regis. Though they are relatively minor figures in the history of ideas, their defence of Descartes's thesis concerning the free creation of the eternal truths, and their emphasis on the importance of experience, provide a unique opportunity to reevaluate the role of experience in the Cartesian philosophy in terms that are common in the period. ;There was a strongly empirical component in the philosophical doctrines and practices of these seventeenth-century Cartesians. Le Grand's view of truth as created and dependent on the will of God led him to assign experiment and experience the role of "making manifest" the operation of laws in the physical universe. Desgabets rejected innate ideas, and argued that all ideas depend on the operation of the senses. Regis emphasized the immutability and total dependence of truths and essences on the free will of God, and thereby undermined the rationalist foundation for the Cartesian doctrine of essences. ;My goal in this approach to the question of the nature and role of experience in the Cartesian philosophy is to explore the philosophical basis of the empiricist tendencies found in Descartes as developed by three of his disciples. My hope is that my study of Le Grand, Regis, and Desgabets, who are relatively unknown today, will not only serve to place them appropriately within the history of ideas, but will dislodge the common misconception of Cartesianism as having been an inherently rationalist philosophy.

We approach the issue of holophrasis versus compositionality in the emergence of protolanguage by analyzing the earliest combinatorial constructions in child, bonobo, and chimpanzee: messages consisting of one symbol combined with one gesture. Based on evidence from apes learning an interspecies visual communication system and children acquiring a first language, we conclude that the potential to combine two different kinds of semiotic element — deictic and representational — was fundamental to the protolanguage forming the foundation for the earliest human language. (...) This is a form of compositionality, in that each communicative element stands for a single semantic element. The conclusion that human protolanguage was exclusively holophrastic — containing a proposition in a single word — emerges only if one considers the symbol alone, without taking into account the gesture as a second element comprising the total message.

In the wake of intensifying debates on decolonisation and restitution in Africa and its francophone diaspora, a Facebook posting of 6 February 2020 gave an other life to a photographic portrait of the French-Italian explorer Savorgnan de Brazza taken in 1882.1 The uploaded digital scan of a photograph from nearly 140 years ago flashed up in a moment of contemporary hypervisibility, offering a visual pretext to denounce de Brazza and the effect of his interventions in Africa virtually and openly on (...) a public post, pulling the image out of the academic and archival environments it had until then mostly inhabited.

In his well‐researched new book, Solidarity and Justice in Health and Social Care, Ruud ter Meulen traces the history of the concept of solidarity and describes the important role that it can play in health care. He contrasts solidarity with other normative concepts, such as autonomy and justice. According to ter Meulen, solidarity entails a commitment and willingness to help others who are “in need of it due to circumstances out of their control” (p. 170). Thus, solidarity exists when people (...) act for the sake of other people who are vulnerable in some way. Ter Meulen treats solidarity as a distinct normative concept and believes that it is critical for health care. No doubt insofar as social ties and cohesion are good for health, so is solidarity.

The recent Supreme Court decision upholding Roe v. Wade and in particular, the dissent by Justice Sandra Day O'Connor, sheds new light on the issue of abortion. Let us consider any stage of a pregnancy when abortion is medically safe for the mother. If at that stage it is also medically viable to save the fetus, is an abortion performed at that stage of pregnancy morally justifiable? For example, if it is, or becomes, medically safe to perform abortions after first (...) trimester of pregnancy and at the same time saving a fetus is, or becomes, medically viable or not unusual during some stage of the second trimester, can abortions during and after that stage of pregnancy be justified? With a number of qualifications I shall argue the thesis that as a general rule, but not an absolute rule, abortion in these instances is not usually justifiable. For if it is, then one will also have to grant the moral justification for a number of other highly questionable medical practices. This thesis is not to be identified with the stronger claim that abortions of viable fetuses can never be performed. There are surely exceptions such as when the life or health of the mother is in danger. But, I shall argue, the justification for making such exceptions is on different grounds than is sometimes claimed because one must weigh the health of the mother against the life of another human being.

I argue, contra Sabina Lovibond, that one cannot defend a viable form of moral realism from the perspective of linguistic conventionalism. Appealing to the later Wittgenstein, I argue that Wittgenstein's alleged linguistic conventionalism rests on the objective ground of the notion of a rule. While Wittgenstein acknowledges that the subjective and social context out of which we operate precludes getting at reality independent of a perspective, neither is he an anti-realist nor does he replace truth conditions with assertibility conditions. If (...) conventions are grounded in the notion of a rule, we can then use this conclusion to defend a form or moral realism. (shrink)

In this article I argue that the famous image on Hobbes’ frontispiece of Leviathan provides a more honest picture of authority and of contract than is provided by today’s liberal images of free and equal persons, who are pictured as sitting round a negotiating table making a decision as to the principles on which to base laws. Importantly, in the seventeenth century, at the start of modern political thought, Hobbes saw no contradiction between contractual agreement and subordination. I will draw (...) out these arguments by comparing three images of politics that employ the human body: Hobbes’ frontispiece is compared firstly with an earlier picture of the state, the illustration of the Fable of the Belly, and then with a later Rawlsian image of the social contract described above. At stake is Hobbes’ view of two associated concepts: authorship and authority. I argue that Hobbes’ image is a vivid portrayal of a ‘persona covert’, akin to the feme covert, a wife characterised in common law as so dominated by her husband that she is imagined as being ‘covered’ by his body.

A crise da representação política e as atuais ameaças às democracias liberais consistem em temas de grande reflexão e debate na filosofia política contemporânea, o que explica, em parte o renovado interesse pelo conceito de representação política. O presente artigo defende que a compreensão das ideologias políticas, a partir da abordagem morfológica de Michael Freeden, possibilita novas formas de pensar sobre a representação e sua relação com a democracia. Ao atribuírem significados determinados e estáveis a conceitos políticos essencialmente contestados, as (...) ideologias disputam o controle da linguagem política, desempenhando também uma função integrativa, ao vincular simbolicamente o indivíduo à sociedade a qual pertence, permitindo, assim, o compartilhamento de conteúdos da consciência individual. A partir da obra de Nadia Urbinati, defende-se a centralidade da recuperação da dimensão ideológica da política para uma noção de representação efetivamente democrática, o que passa pela compreensão do papel deliberativo das ideologias e o caráter híbrido destes sistemas de pensamento, que agregam elementos racionais e não-racionais.

Unlike other works in philosophy of law, which focus on the nature of law in the abstract, this comprehensive anthology presents law as a "process," part and parcel of a system of government and defined constitutional procedures. Using the U.S. legal system as a model, it establishes the basis of law in political theory, then presents substantive issues in private and public law, illustrated throughout with important political documents and court cases and stimulating readings in history, law, and philosophy. The (...) editor's detailed critical commentary, notes, and study questions make these materials accessible and useful for a wide range of readers seeking a deeper understanding of private and public law and the nature of the political process.

Thompson (1994) proposed a re-visioning of the oikos/polis dichotomy in classical philosophy. She offers a dual systems paradigm based on two ancient Greek mythemes---Hestia, goddess of the oikos, or domestic “homeplace,” and Hermes, god of the polis, or public “marketplace,” as an alternative to gender as the primary analytic lens to advance feminist theory. This paper applies hestian/hermean lenses of analysis, described in two propadeutic papers (SPCW 1996; 1997), to the writings of 6th-5th century BCEPythagorean women philosophers and 19th century (...) domestic scientists to claim them as moral philosophers of the hestian domain.

Christine Battersby has argued that it is Kant who provides the paradigm model of what it is to be a self in modernity. The Kantian self is established in opposition to its other. The body is commonly envisaged as a container, with selfhood as something that is defended against the outside. In contrast, she proposes a feminist reworking of such a model of selfhood, applicable to both men and women, in which the self and other emerge over time through patterns (...) of relationality. This paper introduces Battersby’s work by focusing upon her early analysis of Kantian aesthetics, in particular the sublime. The aim is to draw out some of the legal and political implications of her work, particularly with regard to the common law’s developing conception of privacy. This is carried out by distinguishing her ontological position from the psychology of Carol Gilligan and then by considering the overlapping concerns of Jennifer Nedelsky in the area of legal theory.

In Aaron and Bachalo's work, Doctor Stephen Strange exemplifies the characteristics and methods of the natural philosophers in clashes with his mystical enemies, Lord Imperator and the Empirikul. It's easy to be distracted by Doctor Strange's fancy spells, unique job title, or flashy cape, but we should also recognize that he is a Sorcerer Supreme, who demonstrates both discipline and intellect. Like the historical philosopher‐scientists, Doctor Strange studies metaphysics and its relationship to the physical world. When intellectuals began to challenge (...) Aristotle's teleological world‐view, they faced opposition from both the Catholic Church, who found Aristotle's views consistent with scripture, and the scientific community. Historian Peter Dear's book Revolutionizing the Sciences helps situate the work of ancient philosophers, like Aristotle, in the context of the history of the scientific revolution. (shrink)
